The difference between 24GB of the Vengeance at 1600 9-9-9 vs. the 24GB PI at 1600 6-8-6 is going to be very minimal. Im talking less than 1% in most benchmarks. You get a lot of performance from trcd which is only 8 vs 9, cas 6 vs cas 9 isnt a huge difference. Whether or not that is worth an extra $230 that is your call To me, definitely not.

I should also add that there is also no guarantee that 3 kits are going to run at that speed with 6-8-6 as the specs are per kit. I would guess they would but you never know.

first off i cant stand corsair memory anymore
if you get the 8.16 revision its a nightmare

gskills got the best ram these days \they dont bin tight like corsair

that gskills kits eldonko posted is killer
cas6 with 4gb sticks
980x imc is strong
odds are to run6 stix gonna be easier with lower speed + lower cas than higher speed
that ram would be my first choice
and anything that can run cas 6 can do 2000mhz+

As far as I thought (when I used to study this stuff before I built my rig / 2 years ago) the less Cas the better, no matter the Mhz and thats why I went with 12GB Cas 7, from OCZ. To be honest I am not that disappointed but since I have the choice to double up the Ram size and get something more rock solid nowadays thats why I'm looking for something new.

@Eldonko I see your point and you are definitely right but that Cas 6 on 24GB I've never seen it before. It's shocking. So I go with Vengeance ?

@zsamz_ How come you bought the Ripjaws and not the Vengeance? Vengeance looks cheaper and much less timings. Is it for the Mhz?

One cautionary note: According to data compiled by CERN, odds of suffering a single-bit in-memory data corruption with 24GB of non-ECC RAM installed and addressable is 7.2%. Data corruption can suck at the best of times, but when it happens in-memory, it can lead to the entire filesystem being pooched.

Meanwhile, with ECC RAM, the odds of suffering an unrecoverable double-bit in-memory data corruption with 24GB installed is just 0.000005%.

Take that for what it's worth. Obviously not all systems demand that kind of security - e.g., ECC is turned off in all of my folding boxes no matter how much RAM they have. But you better believe it's turned on in my fileserver.

Interesting information, but what do those numbers represent? I mean, 7.2% of what?
